Abstract

Drugs consumption like gentamicin caused damage and decreased of kidney function. Cassava leaf contain lots of micronutrients, such as vitamin C, vitamin A and carotenoids, which also as an antioxidant. The results of the study conducted by Almashuri proved that cassava leaf have high levels of carotenoid compounds. The purpose of this study was to determine the effect of cassava leaf extract on the repairment of renal damage in mice in vivo. This research is true experimental using mice (mus musculus) and were grouped into 5 groups. Two control groups (positive and negative) and 3 treatment groups (cassava leaves 150, 300, and 450 mg / day). Gentamicin is given every day for 14 days and then observed on serum levels of creatinine along with histopathological scores of kidneys’ damage. Statistical analysis showed a significant reduction in serum levels of creatinine (P <0.05) and a significant decrease in renal histopathologic score. This study suggests that cassava leaf extract can repair kidney damage as a result gentamicin-induced nephrotoxicity in mice.Keywords: cassava leaf extract, creatinin, kidney histopathology

Abstract

Bercak darah dapat ditemukan di tempat kejadian perkara (TKP) pada banyak kasus tindak kekerasan. Asam deoksiribonukleat (DNA) pada darah dapat digunakan sebagai data primer untuk proses identifikasi akan tetapi bercak darah di TKP berisiko rusak akibat pajanan tanah dan ultraviolet. Tujuan utama dari penelitian ini adalah untuk mempelajari efek kombinasi dari pajanan sinar ultraviolet-C dan tanah terhadap kualitas dan kuantitas DNA pada bercak darah. Sebanyak 20 gelas berisi 200 gram tanah ditetesi 900µl darah dan diberikan pajanan sinar ultraviolet-C dalam tiga kelompok berdasarkan durasi pajanan yakni satu hari, tiga hari, dan lima hari. Satu kelompok digunakan sebagai kontrol. Ekstraksi DNA dilakukan menggunakan DNAZol dilanjutkan dengan pengukuran spektrofotometri untuk mengetahui kualitas dan kuantitas DNA. Peningkatan konsentrasi DNA dapat diamati yaitu 681,1 pada hari pertama menjadi 1274,7 pada hari ketiga dan mulai menurun menjadi 1090,6 pada hari kelima, sedangkan kemurnian DNA terus menurun secara konstan seiring dengan meningkatnya durasi pajanan. Penelitian ini menunjukkan bahwa pajanan sinar ultraviolet-C dan tanah menyebabkan degradasi molekul DNA menjadi fragmen-fragmen molekul yang lebih kecil sehingga terjadi peningkatan kuantitas DNA yang disertai penurunan kualitas DNA. Penurunan kualitas DNA dapat mempersulit proses identifikasi sehingga isolasi DNA sampel pada tanah terbuka yang terpajan matahari harus dilakukan sesegera mungkin.

Abstract

Diazinon is an organophosphate pesticide often used by farmer. The residue of diazinon may contaminate agricultural products and if accidentally consumed in a long term, may potentially led to health problems such as kidney disorders. Shallot (Allium cepa) peel was recently proposed to help recover the kidney damage due to its high flavonoid antioxidant content. This study aims to determine the antioxidant effect of shallot peel extract in reducing oxidative stress caused by diazinon with malondialdehyde (MDA) level indicator on the kidney of Wistar rats (Rattus norvegicus). This research was a true experimental with an in-vivo posttest-only control group design. The 28 rats were divided using a simple random sampling technique. The groups were the control group (K0), the diazinon group (K1), SPEE (Shallot Peel Ethanol Extract) groups which are P1 (300 mg/kg BW), P2 (600 mg/kg BW), P3 (900 mg/kg BW), P4 (1200 mg/kg BW) and P5 (2400 mg/kg BW). At the end of the study, the MDA kidney levels was analysed using the TBARS method. Effective doses were found in 600 mg/kg BW/day, 900 mg/kg BW/day, 1200 mg/kg BW/day, and 2400 mg/kg BW/day. The optimal dose of shallot peel extract in this study was 600 mg/kg BW/day. This study showed the effectiveness of shallot peel extract in reducing kidney MDA levels in diazinon-induced Wistar rats.

Abstract

Interaction of Cysteine-rich Interdomain Region (CIDR)α-Plasmodium falciparum Erythrocyte Membrane Protein (PfEMP1) and Endothelial Cell Receptors especially CD36 on host cells is main malaria pathogenesis, makes this domain as a malaria vaccine candidate. Recently, the development of the malaria vaccine is conducted by recombinant technology, and the purification of the CIDRα-PfEMP1 recombinant protein is a pivotal step. This study aimed to determine an optimal condition to purify the CIDRα-PfEMP1 recombinant protein by affinity chromatography through imidazole and NaCl concentration. The purified recombinant protein was visualized using SDS-PAGE and its concentration was measured using Image J software and Bradford Assay. The data were analyzed using SPSS 26 software, and the Paired T-Test analysis was conducted to compare the concentration of purified recombinant protein from two different methods. The result showed that thetarget band of purified recombinant protein was 27 kDa. The thickest target protein band was observed in purified recombinant protein using 140 mM imidazole and 300 mM NaCl. The recombinant protein concentration using Image J software was 0.025 µg/µL, while the Bradford Assay was 0.56 µg/µL. The Paired T-Test analysis has a significance value of 0.010 (p<0.05), meaning there was a significant difference between the concentration measurement using Image J software and Bradford Assay. In conclusion, the optimized condition to purify the CIDRα-PfEMP1 recombinant protein by affinity chromatography was using 140 mM imidazole and 300 mM NaCl. It is suggested to measure the purified CIDRα-PfEMP1 recombinant protein concentration using the Bradford Assay method due to its convenience and sensitivity.

Abstract

Recently, a new biomarker of mosquito bite has been developed using human antibody response to mosquito salivary protein. One of the proteins that has been tested is salivary protein 34-kDa which has been refined to Nterm-34 kDa peptide. This study aimed to characterize Nterm-34 kDa salivary peptide as a potential antigen biomarker to asses Dengue virus transmission risk. The sequence Nterm-34 kDa was analyzed using several software to predict the characteristic of the peptide. BLASTP from Vectorbase and NCBI wa used to check the specificity of the peptide. IBIVU Praline was used to do multiple sequence alignment. IEDB (Bepipred and Kolaskar & Tongaonkar antigenicity prediction) was used to predict epitopes and antigenic properties, and lastly, ProtParam was used to predict physicochemical properties. The result showed that Nterm-34 kDa salivary peptide is specific to the  Aedes aegypti mosquito at the species level and has low conservation compared to other proteins in Aedes aegypti 34-kDa salivary protein family. Nterm-34 kDa is predicted to be antigenic and one of the epitopes. Nterm-34 kDa salivary peptide is predicted to have a molecular weight of 2,092 kDa, unstable, and hydrophilic. In conclusion, Nterm-34 kDa salivary peptide is predicted to have potential as an antigen biomarker for Dengue virus transmission.

Abstract

Penggunaan diazinon secara ekstensif menimbulkan dampak buruk terutama bagi pekerja di bidang agroindustri. Efek karsinogenik dan toksik diazinon pada organ terjadi melalui jalur stres oksidatif. Flavonoid kuersetin yang terkandung dalam kulit bawang merah (Allium cepa L.) dapat menetralisir kondisi stres oksidatif, terlebih turunan kuersetin, 2-(3,4-dihydroxybenzoyl)-2,4,6-trihydroxy-3(2H)-benzofuranone (BZF), mempunyai efek antioksidan jauh lebih tinggi dibandingkan kuersetin. Studi ini bertujuan mengetahui efek antioksidan ekstrak etanol kulit bawang merah (EKBM) terhadap stres oksidatif pada tikus Wistar terpapar diazinon melalui pengukuran kadar AOPP plasma dan memprediksi target protein BZF. Sebanyak 25 ekor tikus Wistar jantan dibagi dalam kelompok normal, kontrol, dan tiga kelompok perlakuan. Diazinon per oral diberikan dengan dosis 40 mg/kgBB pada 7 hari pertama, dilanjutkan EKBM dengan dosis 600, 900, dan 1200 mg/kgBB pada 7 hari berikutnya. Kadar AOPP plasma diukur dengan metode kolorimetri Witko-Sarsat. Analisis karakterisasi BZF dilakukan dengan pendekatan bioinformatika Swiss Target Prediction. Kadar AOPP pada ketiga kelompok perlakuan secara signifikan lebih rendah dibandingkan kelompok normal (p<0,05) dan antara dosis 600 mg/kg BB dan 900 mg/kgBB menunjukkan perbedaan tidak bermakna (p>0,05). Karakterisasi BZF menghasilkan prediksi target protein, yaitu pada Kanal Potasium Kv1.3 (skor probabilitas >0,65) yang berperan dalam proses inhibisi reaksi oksidasi protein. Sebagai kesimpulan, pada penelitian ini EKBM dengan dosis 600 mg/kgBB paling efektif untuk menetralisir stres oksidatif akibat paparan diazinon yang ditunjukkan dengan penurunan kadar AOPP plasma. BZF diprediksi memiliki target protein dengan probabilitas tertinggi, yaitu pada Kanal Potasium Kv1.3.
